Help with pistons and rods

[1972orangebeast]

I am looking at purchasing these for an LA 360, Im running a Eddy 360 heads, not decking block or anything. Any idea of what compression itll make? Also these have rods on them and was set up for a magnum motor, will rods and pistons interchange on la to magnum?

Probe SRS 12351-030 piston.

yes but the compression is the issue the mag head has a small combustion chamber you need to calculate true compression

There are too many stack up's and unknowns. Numbers out of a book are just that, numbers. The only way to know is to check your parts yourself. Here's a thread on how to check your engine's compression:

I understand , just tying to get to a rough idea, are these like 14:1 or like 9:1? It's a street motor and want to run on pump gas, just making sure they will.

with dish pistons and eddy close chamber heads...probably around 9.5 to 1....but that is a guess without knowing deck height and head gasket.
